This invention relates to the press apparatus for laminating | stacking a film form material on a board | substrate, or planarizing the film form material on a board | substrate by heating and pressurizing.

4 is a side view showing an example of a conventional press apparatus in which a film form material is laminated on a substrate by pressurization and heating, and the film form material on the substrate is flattened. Such a press apparatus is used, for example, to adhere and adhere a film-like material such as an insulating material or a photosensitive material to the surface of a printed circuit board having irregularities.

The illustrated press apparatus includes a lower base member 1 and a plurality of struts 2 extending upward from the base member 1. The support member 3 which forms the upper part of the press apparatus is attached to the upper end of the support | pillar 2. The upper press block 4 is attached to the lower surface of the support member 3. The upper press block 4 is comprised from the heater plate 5 and the heat insulating material 6. The press apparatus is provided with the movable lower press block 7 in the position facing the fixed upper press block 4. The lower press block 7 is also composed of the heater plate 5 and the heat insulating material 6, similarly to the upper press block 4. The lower press block 7 is attached to the lower support member 8. The lower support member 8 is slidably attached to the support 2 via the guide member 9.

The drive device 10 is provided between the lower support member 8 and the base member 1. In the example shown in figure, the drive apparatus 10 consists of several hydraulic cylinder apparatus. By operating the drive device 10, the lower press block 7 supported by the lower support member 8 can be lifted with respect to the upper press block 4.

The operation of the conventional press apparatus will be described. First, as shown in FIG. 4, when the lower press block 7 is in a downward position, the upper pressurizes the board | substrate 11 which has the film-form material 12 on the surface by a conveying apparatus (not shown). It loads in between block 4 and lower press block 7. Thereafter, the lower pressure block 7 is lifted by the drive device 10, and the upper pressure block 4 and the lower pressure block 7 contact or approach the film-like material 12 on the surface of the substrate 11. In one state, the substrate 11 and the film-form material 12 are heated to a predetermined temperature by the heater plates 5 of the upper and lower pressure blocks 4 and 7. Thereby, the film form material 12 is moderately softened.

After the predetermined temperature is achieved, the lower pressing block 7 is further raised by the driving device 10, and the substrate 11 and the film-like material 12 are predetermined between the upper and lower pressing blocks 4 and 7. Pressurized by the pressure of.

After the pressurization is performed for a predetermined time, the lower pressurizing block 7 is lowered by the drive device 10, separated from the upper pressurizing block 4, and becomes the position shown in FIG. The board | substrate 11 which the film form material 12 adhere | attached closely and laminated | stacked is carried out from a press apparatus by a conveying apparatus.

In the conventional press apparatus of the structure mentioned above, there existed a problem from the point of maintenance. That is, in the structure of the conventional press apparatus, since the up-down stroke of the drive device for raising and lowering the lower press block cannot be taken large, the space of sufficient magnitude was not obtained between the upper press block and the lower press block. Therefore, maintenance workability, such as cleaning of the pressurization surface of an up-and-down pressurization block, replacement | exchange of a component, was very bad, and it was also difficult to visually confirm conditions, such as a scratch of a pressurization surface. Missing scratches, etc. on the pressurized surface will affect the quality of the product after pressurization.

Accordingly, the problem to be solved by the present invention is to provide a press apparatus having a configuration that can facilitate maintenance work.

FIG. 2 is a top view of the press apparatus, and FIG. 2A shows a state in which an upper pressure block is locked and fixed, and FIG. 2B shows a state in which an upper pressure block is locked and pivotable.

The press apparatus is provided with the lower base member 13 and the some support | pillar 14 extended upward from the base member 13. The frame member 15 which forms the upper part of the press apparatus is attached to the upper end of the support | pillar 14. As can be seen from Fig. 2, the frame member 15 in the present embodiment has a pair of bar members 15a and 15b, each of which is attached to the upper ends of the two struts 14. However, the frame member 15 may consist of an integral frame body, and may be a structure connected in at least one place.

The upper support member 17 which attached the upper press block 16 to the upper surface is conically joined to the frame member 15. In detail, the through-hole 18 is formed in one side part of the upper support member 17, ie, the side part of the right side in FIG. 1 and FIG. In one side portion of the pair of bar members 15a and 15b of the frame member 15 adjacent to the one side portion of the upper support member 17, a hole 19 is formed which is matched with the through hole 18, respectively. have. The shaft 20 is inserted into the through hole 18 and the pair of holes 19. The diameters of the through hole 18, the hole 19 and the shaft 20 are set such that the shaft 20 functions as a pivot shaft member for the upper support member 17 and also receives a load at the time of pressing. do.

A pair of holes 21a and 21b are formed in the side portion facing the one side portion of the upper support member 17, that is, the left side portion in FIGS. 1 and 2. In addition, in the pair of bar members 15a and 15b of the frame member 15 adjacent to the left side of the upper support member 17, the holes 22a and 22b to be matched with the holes 21a and 21b are provided. Each is formed. Engaging pins 23a and 23b can be inserted into these holes 21a, 22a, 21b, and 22b, respectively. When the upper support member 17 is not pivoted around the shaft 20, as shown in FIG. 2A, each of the pins 23a and 23b is formed by the holes 21a and the upper support member 17. It is positioned so as to extend over both the holes 22a and 22b of the pair of bar members 15a and 15b of the pair of bar members 15a and 15b of the frame member 15, and the upper support member 17 and the frame member 15 are hooked. Fix it. In this state, the apparatus can have the same rigidity as the conventional press apparatus. On the other hand, when the upper support member 17 permits to pivot around the shaft 20, as shown in Fig. 2B, each of the pins 23a and 23b is drawn inward, and a pair of It becomes the position deviating from the holes 22a and 22b of the bar members 15a and 15b. As a result, the upper support member 17 is released from the engagement with the frame member 15, so that the upper support member 17 can pivot around the shaft 20. On the other hand, even if the pins 23a and 23b are pulled out and removed from the holes 21a and 21b of the upper support member 17, the pivoting movement of the upper support member 17 becomes possible.

The means for pivoting the upper support member 17 is a drive device 24 provided between the base member 13 and the upper support member 17. The drive device 24 includes a cylinder device having a cylinder 25 and a rod 26, and a lever 27. The lower end of the cylinder 25 is conically joined to the base member 13. One end 27a of the lever 27 is conically joined to the upper end of the rod 26. The other end 27b of the lever 27 is fixedly attached to the upper surface of the upper support member 17.

As shown in FIG. 2B, when the pins 23a and 23b are in a position to release the engagement state between the upper support member 17 and the frame member 15, the rod 26 is shortened by operating the cylinder device. In other words, the upper support member 17 pivots upward around the shaft 20 as shown in FIG. 1B.

The upper press block 16 supported by the upper support member 17 has a heater plate 28 and a heat insulating material 29. The lower press block 30 is formed in the position facing the upper press block 16. The lower press block 30 also has a heater plate 28 and a heat insulator 29, but is further provided with a gel material 31 between the heater plate 28 and the heat insulator 29.

The lower press block 30 is attached to the lower support member 32 and is supported by this. The lower support member 32 is slidably attached to the support 14 via the guide member 33.

Between the lower support member 32 and the base member 13, a drive device 35 made of at least one hydraulic cylinder device 34 is provided. By operating, the drive device 35 can raise and lower the lower press block 30 supported by the lower support member 32 with respect to the upper press block 16.

By operating the drive device 35 to bring the lower press block 30 closer to the upper press block 16 provided thereon, carried in between the lower press block 30 and the upper press block 16, The series of operations for heating and pressurizing the substrate 11 having the film-like material 12 on the surface and laminating the film-like material 12 on the substrate 11 in close contact with each other is almost the same as in the case of the conventional press apparatus. Since there is no change, the detailed description is omitted. In other words, in the press apparatus according to the embodiment of the present invention, since the lower press block 30 includes the gel material 31, the drive device 35 is one hydraulic cylinder device 34. It is possible to uniformly disperse the pressing force by the gel material 31, whether or not it is constituted by a plurality of hydraulic cylinder device (34). Therefore, the board | substrate 11 and the film form material 12 can be pressurized by uniform pressure distribution. In the present embodiment, the gel pressing material 31 is provided only in the lower pressing block 30. The gel pressing material 31 may be provided in both the upper and lower pressing blocks 16 and 30. The gel material 31 may be provided only in (16), and the same pressure dispersion effect may be obtained by using a sol material or a member encapsulated in place of the gel material 31. .

At the time of maintenance of a press apparatus, the pin 23a, 23b is pulled out from the hole 21a, 21b of the upper support member 17, or the hole 22a, 22b of the frame member 15 as mentioned above, The engagement between the support member 17 and the frame member 15 is released. Thereafter, the driving device 24 is operated to cause the pivoting motion around the shaft 20 to the upper press block 16 supported by the upper support member 17, thereby lowering the press block 30 and the upper press block ( 16) Increase the space between. As a result, it is possible to easily clean the pressing surfaces of the upper and lower pressing blocks and check the state of scratches on the pressing surfaces with eyes.

3 is a fragmentary enlarged view showing a modification 23c of the pin and its peripheral member. The pin 23c has two enlarged diameter portions 23d and 23e having a diameter D, and a reduced diameter portion 23f having a diameter d formed therebetween. In the figure, the pin 23c is inserted into the holes 21a and 22a formed in the upper support member 17 and the frame member 15 to fix the upper support member 17 and the frame member 15 to each other. It is. When the film-like material and the substrate are pressed at this time, the force applied to the frame member 15 from the upper support member 17 through the pin 23c to generate a moment on the upper end of the support 14 is enlarged. It acts on the working point S in the interface between the diameter part 23d and the reduced diameter part 23f. For example, assuming that the pin does not form the reduced diameter portion 23f and has a uniform diameter D, the force applied to the frame member 15 through such a pin is a frame member (with which the pin is inserted) It will act on the point of action S1 at the end surface of the hole 22a of 15). Comparing these two cases, the working point (S) side is located closer to the central axis of the support 14 than the working point (S1). Therefore, when the pin 23c having the reduced diameter portion 23f is used, the arm length of the moment M generated at the upper end of the support 14 is shortened, so that the value of the moment M can be reduced. .

The shape of the pin 23c shown in FIG. 3 can also be applied to the pivot shaft member 20 in the hole 19. That is, the pivot shaft member 20 also has a reduced diameter portion and other enlarged diameter portions, and the interface between the reduced diameter portion and the enlarged diameter portion can be positioned near the central axis of the support 14. In this case, the upper support member 17 and the frame member 15 are in a locked state by being caught with each other, and when the film-like material and the substrate are pressed, the upper support member 17 to generate a moment on the upper end of the support 14. The point of action of the force exerted on the frame member 15 through the pivot shaft member 20 is at the interface between the enlarged diameter portion and the reduced diameter portion located in the hole 19 near the central axis of the support 14. . Assuming, for example, that the pivot axis member 20 did not have a reduced diameter, the operating point would be present at the end surface of the hole 19. As in the case of the pin 23c described above, by forming the reduced diameter portion in the pivot shaft member 20, the length of the arm of the moment generated at the upper end of the support 14 can be shortened, so that the moment can be made small. do.

In this way, by devising the pin and pivot shaft member to reduce the moment occurring at the upper end of the support 14, the support 14, which is not required to withstand large moments, can be made smaller in diameter. Can reduce the weight of the entire apparatus.

The press apparatus which concerns on this invention is applicable to a vacuum press apparatus. In this case, the lower pressurizing block and the upper pressurizing block are provided in the vacuum chamber, and the pressurization of the substrate and the film-like material laminated thereon is performed in a reduced pressure atmosphere of the vacuum chamber.

When constructing a vacuum chamber, the upper support member may form part of the vacuum chamber.

According to the press apparatus of the present invention, since a sufficiently wide opening can be formed between the upper press block and the lower press block at the time of maintenance, cleaning of the press surface of the upper and lower press blocks, replacement of parts, and eye It becomes easy to check a state, such as a scratch, etc., and water retention improves.
